Partially hyperbolic diffeomorphism by surgery

In this posting I will explain a surgery construction of a weakly partially hyperbolic diffeomorphisms on a closed 3-dimensional manifold. A diffeomorphism is weakly partially hyperbolic if it admits an invariant dominated splitting , where is uniformly contracting. 929 more words

Complete lecture videos for last week’s workshop Computation in Geometric Topology at Warwick are now posted on YouTube. The complete list of talks with abstracts and video links is here.


Bing's wild involution

An embedded circle separates the sphere into two connected components; this is the Jordan curve theorem. A strengthening of this fact, called the Jordan-Schoenflies theorem, says that the two components are disks; i.e. 2,426 more words
